Exam CRT-450 topic 1 question 329 discussion

A. The method must use the @AuraEnabled annotation to make it accessible to Lightning web components and Aura components. C. The method must be defined as static since it's called from a Lightning component. D. The method must be defined as public to ensure that it can be accessed by other Apex classes, including the Einstein Next Best Action process builder action. The @InvocableMethod annotation is used for process builder actions that accept parameters. The @Future annotation is used for asynchronous Apex methods.

A. The method must use the @AuraEnabled annotation. The @AuraEnabled annotation makes the method accessible in Lightning components, which is necessary for Einstein Next Best Action. B. The method must use the @InvokableMethod annotation. The @InvokableMethod annotation allows the method to be called from Flows or Einstein Next Best Action. C. The method must be defined as static. The method needs to be static when using @InvokableMethod to ensure it can be called without creating an instance of the class. D. The method must be defined as public. The method doesn't have to be public, but it must be accessible to the relevant components or processes.

https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_annotation_InvocableMethod.htm As explained in the intro and in considerations @Invocable method must be static and public or global

C. The method must be defined as static: To be callable from an external context or as part of an invocable action, the method should be defined as static. D. The method must be defined as public: The method should be defined as public so that it can be accessed from outside of the class. E. The method must use the @Future annotation: To perform a callout to an external system asynchronously, the method should use the @Future annotation. This allows the method to run in the background without blocking the main transaction.

Ok... I think the Apex method in the context is about the callout. Then CDE are a correct answer.

I think E is correct at least. Because to perform callout @future might be used.
